TOPEKA, Kan. (AP) — Authorities are investigating two deaths in a central Topeka apartment as “suspicious” in nature.

The Topeka Capital-Journal reports that police were notified Monday morning. Topeka police Lt. Colleen Stuart says foul play hasn’t been ruled out as a cause of the deaths.

The name of the victims weren’t immediately released. It wasn’t known how long the individuals had been dead.

An animal control officer was seen carrying a small pet crate out of the building shortly after detectives and officers had arrived at the scene. A representative of the Shawnee County District Attorney’s Office also came to the apartment complex.
